Validation of eAircraft battery simulation approach using field measurement data

Abstract

Due to the specifically high power pulse and long duration energy requirements against lithium battery systems in electric aircrafts, the electrical design cannot be realized without sufficient modeling and simulation of such batteries considering the nonlinear behavior of cells and mission profiles. This paper presents an overview of the simulation approach and confirms the performance for using it as a design tool. The validation process of the models and simulation environment in MATLAB/Simulink includes error analysis investigating real measurement data recorded during flights of a fully electric aircraft.
